Parameter	Description

Return

Return	Description
NOS_OK	Kernel started successfully.
NOS_E_RUNNING	Kernel already started.

Notes

1. It is suggested to start your systick timer in callback.
2. User callback is called outside of critical section, then interrupts can be re-enabled in callback.

Example

#include "nOS.h"

void Systick_Start(void)
{
    // Initialise timer that will be used as system tick at *NOS_CONFIG_TICKS_PER_SECOND* frequency
    // Start timer
}

void main(void)
{
    disable_interrupts();

    nOS_Init();
    // Application specific init

    // nOS objects creation

    nOS_Start(Systick_Start);

    enable_interrupts();

    // ...

    while (1) {
        // Idle

        // ...
    }
}
